The GraviTrax Advent Calendar hides 24 gifts and an extra surprise. Behind each door of the Advent calendar, there is at least one surprise, ranging from building blocks to action stones and festive ornaments. Especially beginners and GraviTrax fans will be excited about 8 special curve stones. The 24 surprises, along with the extra surprise, can be experienced with or without a starter set. A Christmas track and explanations of the individual action stones are included in the app.

With GraviTrax, building fun knows no bounds. The GraviTrax marble run system can be infinitely expanded with extensions, ensuring limitless building and play enjoyment. By freely designing the marble tracks and exploring the rolling and flying behavior of the marbles, an understanding of science is sharpened, and gravity is made tangible. The STEM label on our products indicates a play category that allows for playful experiences with science. STEM (Science, Technology, Engineering, Mathematics) corresponds to the German MINT (Mathematics, Computer Science, Natural Sciences, Technology).
